Obama says the ideas that are on the table include stronger background checks, a meaningful ban on assault weapons and limits on high-capacity ammunition magazines.

As the White House looks for limits on guns and ammunition, it faces opposition from the well-funded and politically-powerful National Rifle Association and its supporters in Congress. Obama can use his executive powers to act alone on some gun measures, but his options on the proposals opposed by the NRA are limited if Congress doesn't go along.

Obama is reviewing a series of proposal from Vice President Joe Biden. He had asked Biden to lead a task force on ways to reduce violence after last month's elementary school shooting in Connecticut.
